Enter the initial and final volume, along with the initial and final pressure, into the calculator to determine the bulk modulus.

## Bulk Modulus Formula

The following equation used to calculate the bulk modulus of a material.

B = -V1 * (P2-P1)/(V2-V1)

- Where B is the bulk modulus
- V1 is the initial volume
- V2 is the final volume
- P1 is the initial pressure
- P2 is the final pressure

## Bulk Modulus Definition

A bulk modulus is defined as the measure of elasticity of the material or gas to expand or contract while under a pressure.

## FAQ

**What is Bulk Modulus?**

Bulk modulus is a measure of the bulk elasticity of a material or object. In other words, it’s a measure of how resistant to pressure the material is.

**How is bulk modulus calculated?**

The bulk modulus is calculated by measure the volume and pressure of an object at two different points.
